- a smoothing capacitor 28 with a discharge resistance 30 mounted in parallel is provided between the two output terminals of the rectifier 22 , as well as a sensor 32 for measuring the voltage at the terminals of the direct bus 26 .
- the traction motors 14 are each powered by a respective IGBT traction inverter 34 .
- Each inverter 34 is made up of three branches, each formed by two one-way switches 35 connected serially. These three branches are connected to the two direct inputs of the inverter. The three outputs for the three-phase current of the inverter are taken between the two one-way switches 35 of each branch.
- Each one-way switch is formed, as known in itself, by an IGBT transistor and a diode mounted in anti-parallel.
- Each inverter 34 is equipped with a control unit 36 able to control the one-way switches 35 , for example following a pulse width modulation law so as to power the associated traction motor 14 so that it supplies the required power. To unclutter the drawing, only certain control units 36 are illustrated.
- the inputs of the traction inverters 34 are connected in parallel by threes to the direct bus 26 via two power branches 37 provided with two sectioning switches 38 , each mounted serially with a decoupling inductor 40 , which in turn is mounted in parallel with a resistance 42 .

- a voltage sensor 92 is provided at the input of the inverter 82 .
- the output of the inverter 82 is connected to a three-phase step-up transformer 98 through a three-phase contactor 100 .
- the step-up transformer 98 has a transformation ratio greater than 1 and in particular between 1 and 3.
- the step-up transformer 98 powers, as output, a three-phase power supply grid 101 of the industrial type, for example having an effective voltage of 480 V and a frequency of 60 Hz.
- Three trimmer capacitors 102 are arranged between the phases of the power bus 101 as output of the transformer.
- the IGBT transistors of the inverter 82 are piloted by a control circuit 103 able to ensure a voltage equal to 480V and 60 Hz on the three-phase power supply grid of the auxiliary loads.
- the power bus 101 is equipped with two direct voltage sensors 104 , 106 connected to the bus by two diode rectifier bridges 104 A, 106 A.
- the sensor 104 is connected to the control circuit 103 and the latter ensures the piloting of the transistors from the measured voltage to ensure regulation.
- step-up transformer 98 makes it possible to reach such a voltage, even when the engine 12 idles and the voltage on the direct bus is equal to 600 V.
- a bypass 120 ensures the connection between the output of a traction inverter 34 for powering a traction motor 14 and the input of the step-up transformer 98 .
- This bypass is equipped with a controllable back-up three-phase contactor 122 .
- three controllable switches 124 are provided between the considered traction motor 14 and the bypass 120 .
- the switches 100 , 122 and 124 are controlled by a pilot unit 126 so that the switches 100 and 124 are in a same state and the switches 100 , 124 on the one hand, and 122 on the other hand, are in opposite states, so that the output of the traction inverter 34 is only connected to one of the transformer 98 and the traction motor 14 and the inverters 82 and 34 are never located on the same three-phase grid.
- the unit 126 is connected to the control unit 36 of the inverter 34 so that, when the output of the traction inverter 34 is connected to the step-up transformer 98 , the control unit 36 of the inverter applies a control law adapted to obtain, on the grid 101 , a voltage of 480 V under a frequency of 60 Hz.
- the sensor 106 is connected to the control unit 36 so that the latter regulates the voltage on the bus 101 by controlling the transistors by an adapted control law, i.e. a control law identical to that of the control circuit 103 , if the inverters 34 and 82 are identical.
- the diesel engine 12 is connected to a control unit 200 , ensuring its piloting and in particular the rating of the engine as a function of the overall electrical power needs.
- the unit 200 when the locomotive is stopped, or in braking phase, the unit 200 is able to ensure a minimal supply of fuel oil to the engine 12 so that the latter idles.
- the speed of rotation of the engine 12 is only increased by injecting more fuel oil under the control of the unit 200 during traction phases by the motors 14 .
- the electrical energy provided by the engine 12 is sufficient to power the auxiliary loads 16 , 18 , which are powered with a voltage and a constant frequency of 480V/60 Hz, independently of the engine's speed of rotation owing to the use of the static converter 82 and the step-up transformer 98 .
- the rheostatic choppers 50 are implemented to dissipate the energy reintroduced by the motors 14 through the inverters 34 .
- part of the energy reinjected by the motors 14 is used by the static converter 82 arranged in parallel with the rheostatic choppers 50 to power the auxiliary equipment 16 , 18 through the step-up transformer 98 so that the engine 12 is made to idle, thereby limiting its fossil fuel consumption.
- the presence of the groups of switches 100 , 122 , 124 and the bypass 120 makes it possible, in the event of a malfunction of the static converter 82 , to ensure the power supply of the auxiliary equipment 16 , 18 via a traction inverter 34 , thereby allowing the locomotive to complete its mission, even if the motor 14 normally powered by the inverter 34 that then powers the auxiliary equipment is no longer in operation.
